Abstract

L'invention concerne un procédé pour la production de sels complexes de chlorure de zinc ammoniacal utiles en tant que fondants de galvanisation. Ce procédé consiste à chauffer des déchets provenant de traitements industriels contenant du zinc dans une atmosphère réductrice, à lixivier les déchets capturés obtenus dans une solution de chlorure d'ammonium ce qui nous donne une première solution et des premiers matériaux non dissous, à ajouter du métal de zinc à la première solution ce qui nous donne une seconde solution et des seconds matériaux non dissous et à ajouter du chlorure d'ammonium supplémentaire et/ou de l'acide hydrochlorique à la seconde solution ce qui nous donne des sels complexeS de chlorure de zinc ammoniacal utiles en tant que fondants de galvanisation.
